摘　　要：在各种网络状嵌入式系统如数字信号处理、车辆跟踪和基础设备监控中,一般同时要求低的能量消耗和低的反应时间。传统的方法通常只集中考虑能量节约问题,而没有考虑最优跨度问题,这样调度长度可能非常长的情况有时让人无法容忍。在限制调度长度的条件下最小化能量消耗,并提出了一种平衡能量消耗和反应时间的算法EATA。实验结果证实了该算法的有效性。Parallel applications with energy and low-latency constraints are emerging in various networked embedded systems like digital signal processing, vehicle tracking, and infrastructure monitoring. However, conventional energy-driven task allocation schemes only concentrate on energy-saving rather than makespan of parallel applications. The situation of the long length of the schedules is unfavorable or even not tolerated. This paper addressed the issue of allocating tasks with an objective of energy-saving and short-latency. Proposed a novel task allocation strategy EATA. Experimental results demonstrate that proposed scheme is effective in a heterogeneous embedded svstem.
